Sacha in a few words

Since my younger age, I always loved IT. 😍
But how did I start into computer science ?🤔

At 16, I was passionate for the radio. 📻
And I needed a website to let people listen to me. 🎧
So I created my first website using Wix and after with WordPress. 👨🏻‍💻

That's how I came into the game of development. 😝
I studied the web development and I now have a master's degree. 👨🏼‍🎓

Today I work into the web3 ecosystem and the blockchain. 🦊
I develop smart contract using Solidity to create something like NFT, ERC20 tokens...

But I also work as a back-end developer using PHP and Symfony. 💻
When managers ask me to develop a part of front-end, I'm able to use Vue.js and Angular.

But I'm not limited to my technologies, I love to learn, create new things and to be challenged !😉
